preset-mcp-discovery skillA

preset-mcp-discovery is agent-read markdown (skill) from preset-io/agent-skills: Use Superset MCP health, instance, list, detail, schema, and chart-type discovery tools. Use only for MCP tool workflows; do not use for direct API work..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add preset-io/agent-skills/preset-mcp-discovery@git:20260611.679740f
Exact content
mdr add preset-io/agent-skills/preset-mcp-discovery@sha256:c7f063e8b27ae862

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
